Writing Clean & Maintainable Code

Why is it important to avoid deeply nested conditionals in JavaScript code?

function processOrder(order) {
  if (order) {
    if (order.items) {
      if (order.items.length > 0) {
        if (order.payment) {
          // Process order
        }
      }
    }
  }
}

To save memory consumption
To improve code execution speed
To reduce cognitive complexity and improve maintainability
Deeply nested conditionals create code that is difficult to read, understand, and maintain. They increase cognitive complexity and make it harder to follow the code's logic flow. Better approaches include early returns, guard clauses, or breaking down the logic into smaller, more focused functions. This improves code readability and reduces the likelihood of bugs.
